On Solaris systems, the UNIX user starting the Cluster Edition must have SYS_DEVICES inheritable privileges to access the raw devices (/dev/raw/raw# or /dev/rdsk/c#t#d#s#) used for databases and quorums.
The SYS_DEVICES privilege grants Adaptive Server the ability to execute SCSI-3 PGR commands used in I/O fencing. The UNIX user can be granted temporary or permanent SYS_DEVICES privileges:
To grant temporary SYS_DEVICES privileges, add SYS_DEVICES privileges to the inheritable privilege set of the current user’s shell process:
ppriv -s l+sys_devices $$
To grant permanent SYS_DEVICES privileges, use the usermod UNIX command to add SYS_DEVICES to the inheritable privilege set of any user:
usermod -K defaultpriv=basic,sys_devices user_login
